14.: Later that day we climbed up the mountain on the other side of the lake in about 5 hours to over 5000m. When we came back, just 10 minutes left to our sleeping place, I collapsed and had to keep lying down for a few minutes, because I had had to little food and was therefore utterly exhausted. Later in Germany I had to find out that the trip and the two month canteen food in Xi’an before costed me about 6 kg of muscle mass to a meager 63 kg.
